FLUSHING-VALVE Specification of Letters Patent.

Patented Nov. 3, 1908.

Application filed April 3, 1908. Serial No. 424,859.

To all whom it may concern:

Be it known that I, FRANK T. GALLON, a citizen of the United States, anda resident of Indianapolis, in the county of Marion and State ofIndiana, have invented certain new and useful Improvements inFlushing-Valves, of which the following, when taken in connection withthe drawing and reference-letters thereon accompanying and forming apart hereof, is a full and complete description, sufficient to enablethose skilled in the art to which it relates to understand, make, anduse the same.

This invention relates to flushing valves used in water closets.

The object of the iuvontionis to obtain a flushin valve of the kindnamed which may be quic ly o cried and which will slowly and automaticaly close.

A further object of the invention is to obtain a flushin valve of thekind named which will be simple in construction, com rising few parts,not liable to get out of or or, requirmg no stuffing box, and which maybe adjusted to vary t e time of closing.

A further Ol)]80t of the invention is to obtain a flushing valve whichwill automatically prevent dirt accumulating on the valve seat therein.

Figure 1 of the drawing is 8..V6Ilii0fil860- tional view of a flushingvalve embodying my invention. Fig. 2 is a sectional view on line 22 ofFig. 1 viewed in the direction indicated by the arrows. Fig. 3 is avertical sectional view of radially extending valve guides on line 3-3of Fig. l viewed in the direction indicated by the'arrows.

A reference character applied to designate a given part is used toindicate such part throughout the several figures of the drawingwherever the same appears.

A is the shell of a flushing valve embodying this invention, a areexternal screw threads at the inlet end of the shell, a are like screwthreads at the outlet end of such shell, and a are external screwthreads on the shell arranged to engage with corresponding screw threadsin cap B is a partition wall in shell A, by means ofwhich the chamber C,hereafter termed the inlet chamber, chamber D, hereinafter termed theputlet chamber and a recessed portion heremaftler termed recessedchamber D are,

obtained Communication between the inlet cha ber and the outlet chamberis estab lished through the apertures E, E, when valves F, F, areunseated.

The flow of water into inlet chamber C, where the supply pipes theretoare of suflicicnt size, is through the large inlet C but where the watersupply pipes are not large enough to obtain suflicient flow of waterthercthrough to properly flush the closet, a water rece tacle, the lowerend of which is shown in ig. 2, lettered A" is attached to shell A as bymeans of screw threads (1, a, and the water flowing into and through theinlet chamber and also into and out from the water rece tacle A isadmitted through the smaller in ct C. When the inlet C is-not in use itis, of course, closed by an. ordinary jl is the stem of valve F, and fis' an annular groove in such stem,

G is a disk at one end of stemf.

H, H, are radially extending guides integral with valve stem f andarranged to form a spider between valves F, F. Valve F is of slightlygreater diameter than valve F, and is secured in position at the end ofthe ppider, as by means of the bolt I. The guides H, are provided withconcave faces 72., on one side, forming the front thereof, and withconvex faces h, on the other side, forming the back thereof. When waterflows from the inlet chamber C through apertures E, E,

into theoutlet chamber D, rotation of the valves F, F, stem f, and disk.G, is obtained;

F, F, comprises the shaft M, weighted han dle N, and fingers O.Thc-fingers are, referably, integral (see Fig. 2) with sha t M.

he fingers O are arranged to enga c with the annular groove f of shaftf, so t at the rocking of the shaft M, by the raising of the handle Ninto substantially the position illustrated in Fig. 1 will unseat thevalves F, F, as is shown in Fig. 1.

P, is a disk integral wlth shaft M and providelfwith the,sea ting facep, which is arran ed to form a valve to seat on face 9 of gui c Q. Faceq forms a valve seat.

R, is a spr' washer and S, are nuts on the screw threade end an of shaftM.

Guide Q, is secured to shell A by means of screw threads Qf arran ed tofit into corres onding screw 'threa s in shell A, (see haft M, isprovided with a number of straight sides or faces m, and the handle N,is provided with a hole having corresponding faces arranged to fit oversuch shaft to rigidly attach the handle to the shaft, so that turningsuch handle will turn the shaft.

S ring washerR, interposed between handle and nuts S, maintain theseatin or valve face p, of disk P, in contact with ace or valve seat qof guide Q, so that no stuffing box is required.

When the valves F, F are unseated and handle N is released the wei htthereof tends to move the stem longitu inally and close such valves.

The longitudinal movement of stem f increases the size of chamber J, andsuch longitudinal movement of the stem is therefore retarded by thereduced ressure thereby created in such chamber and when the valves areseated, the larger area of valve F tends to hold the valves closely ontheir respective seats, preventin leakage theret rough, and the curvingo the guides H, H, produces rotation of the valves which tends to remove(at about the time of the seating of the valves to close the aperturesE, E), any sediment thereon.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is,

1. The combination of a shell provided with artition walls arranged toform an inlet 0 amber and an outlet chamber, such partitions, providedwith apertures therethrough of different diameter, a longitudinallymovable stem, valves on the stem arrangedto control the apertures, adisk on the stem arranged to form the movable wall of an air chamber inthe shell, a passage way through the stem and disk arranged tocommunicate with the air chamber, means disposed transversely of thelength of the stem to adjustably restrict the passage way, radiallyextending guides on the stem between the valves, such uides providedwith concave and convex si es respectively, and a rocking shaft andmeans rigid with the shaft engaging said stem to move the stemlongitudinally and means to automatically return such stem to itsinitial position: substantially as described.

2. The combination of a shell rovided with artition Walls arranged toorm an inlet 0 amber, an outlet chamber and a receseedchamber to oneside ofthe inlet and outlet chambers,. a plurality of inlets to theinlet chamber, an outlet to theoutlet chambar and an open end to therecessed' thamr ber, with the partition between the inlet and outletchambers provided with apertures of different diameters and valve seatsto such apertures, a cap arranged to cover the open end of the recessedchamber, a

valve stein,*adisk on the stem arranged to form the movable Wall of anair chamber located at one end of the recessed chamber, a passage waythrou h the stem arranged to communicate with t e air chamber, means torestrict the ,passage way, valves on the stem arranged to coact with thevalve seats, the larger of such valves removably at tached to the stem,radially extending guides on the stem and between the valves and suchstem provided with an annular groove a rocking shaft, a weighted handleto such rockin shaft outside the shell and fin ers to sucl rocking shaftwithin the she I, such fingers arranged to engage with the annular}groove on the stem, and means to prevent t e flow of water from theshell around the rocking shaft: substantially as described.

3. The combination with a shell provided with artition walls arranged toform an inlet 0 amber, an outlet chamber and a recessed chamber to oneside of the inlet and outlet chambers and such artition -walls providedwith apertures 0 different diameters, with valve seats to suchapertures, and such shell provided With a plurality of inlets to theinlet chamber, of a valve stem, valves on the stem arranged to coactwith the valve seats, the larger of such valves removably attached tothe stem, a disk on the stem, such disk arranged to form the movablewall of an air chamber, a restricted passage way communicating with theair cham er and with the recessed chamber, radially extending guides onthe stem between the valves, such guides provided with concave andconvex faces, and such stem provided with an annular groove, a rockinshaft, a bearing to the rocking shaft, suc

bearing removably attached to the shell and provided with a valve seatat the inner end thereof, a handle on the shaft outside the shell andfingers on the shaft inside the shell, such fingers arranged to engagewith the annular groove on the stem, and a disk on the rocking shaftprovided with a valve on one side thereof arranged to co-act with thevalve seat on the inner end of the rocking shaft bearing: substantiallyas describe HARRY A.
